Hello Dad,
I am no expert, but the last two marks looks like the marks of the city Mons (Dutch and German Bergen) in Belgium.
Kind regards,

Hello, R ingo.

It is fine! I have thought about Mons too. The subject is in Brussels.
Many thanks for your answer and picture.
I think two marks at the left - the silversmith?
